Carter Day Precision Sizers / Graders

Models 1VT, 212, 412, or 612

The Carter Day Precision Grader / Sizer provides methods of sizing or separating various grains and other granular materials by thickness and by width with exactness and
uniformity. They can size and separate seed corn, sunflower, barley, wheat, oats, rice, shelled peanuts, soybeans, seeds, and other free-flowing granular material.

About the Cylinders:

The rotating cylinders present the material to the greatest amount of screen area in the least amount of time for better separations at high volumes. Rotating wiper blades are located at
the top of the cylinders where near-sized material is gently pushed back down into the cylinder without damage to the seed.

Every Precision Sizer is self-cleaning. Each cylinder is also designed with a quick change feature for easy changing of cylinders or for cleaning. Numerous styles and perforation
sizes are available for a wide range of applications.

Round ribbed cylinders have ribs that run the length of the cylinder between each of several rows of round perforations. These ribs provide gentle agitation that up-ends
the material for proper presentation to the perforations. Best for separating small particles by width.

Funlsizer cylinders have funnel shaped round holes. The funnel design up-ends the grain directly into the hole and either allows passage through the hole or rejects the
grain and passes it down the cylinder. Best for separating large particles by width.

Slotted cylinders have rectangular slot perforations with indented grooves. Best for separating particles by thickness with close tolerances.

Tri-bar slotted cylinders can double the cylinder capacity depending on slot width. It operates by using a triangular shaped wire, instead of punched slots, producing more
open area. Rigid construction maintains opening tolerance longer. Best for separating particles by thickness with high capacity.
